In either case the plates P are subjected to an atmosphere of products of combustion, air and moisture and such an atmosphere along with heat exerts a beneficial efiect in drying plates.

The conveyor guides 9 and I0 include spacer pieces, as shown and they support the lower platen 8, when present. The upper platen I rests upon filler pieces and is held to place by the upper oven parts.

It will be obvious to those skilled in the art to which the invention relates that modifications may be made in details of construction and procedure and matters of mere form without departing from the spirit of the invention which is not limited to such matters or otherwise than the prior art and the appended claims may require.

I claim: 1. A machine for drying storage battery plates comprising an oblong two-part heat insulated oven, open at its ends and defining combustion chambers, spaced perforated platens arranged in the upper and lower combustion chambers and defining a treating chamber, a conveyor adapted to engage plate edges and carried by the lower part of the oven and extending through the treating chamber, burners arranged in the combustion chambers above and below the platens, flexible connections for supplying upper burners to permit of the removal of the upper part of the oven, and vents for controlling the atmosphere of the treating chamber.

2. An oven for drying storage battery plates comprising a two part, separable shell open at each end, top and bottom and side refractory linings providing a section of a combustion chamber and arranged in each shell part, spaced foraminous platens, spaced supports between the shell parts and attached to the lower shell part and extending through the casing, conveyor chains arranged on the supports and having side guides, and heating means and ventilation provisions for the combustion chambers 3. An oven for drying storage battery plates, comprising in combination: a two-part, separable shell open at each end and defining combustion chambers; spaced, perforated platens arranged in the upper and lower combustion chambers and defining a treating chamber; a conveyor adapted to engage plate edges and extending through the treating chamber; burners arranged in the combustion chambers above and below the platens; and vents for controlling the atmosphere of the treating chamber.
